I spent a couple of hours this afternoon down at the shore, taking pictures. It was very cold, and bright, with new clouds coming in, in the distance.
It has been very cold at night during the low tides, and the seawater has frozen onto the beaches, underneath the returning tidal water. I've never seen underwater ice before.
And here, visible during this afternoon's low tide, a wave that froze as it came up onto the exposed beach.
